This game does suck. The AI is some of the worst AI I have ever seen in a game. The enemy AI will send units back and forth back and forth for absolutely no reason and never accomplish anything with those units. The enemy AI also never saves up money for any good units. They spend all the money they can each turn so the enemy ends up just spawning massive amounts of cheap ♥♥♥♥♥♥ units. If you have long ranged units it really ♥♥♥♥s up the enemy AI. They don't know how to rush your long range units and will typically always stay outside of their firing range. On one of the mid levels of the game I bottled up the enemy AI in their base right towards the beginning by just stationing my rocket launchers near the 3 exits of their base and they didn't know what to do.

Defensive spots are somewhat pointless because typically whichever unit attacks first is the one that will win because they can do 50-80 damage and then the other unit does almost no damage because it's already been hurt. So trying to hold rocks which have a defensive bonus of 4 is ♥♥♥♥♥♥♥t because the enemy gets to attack your unit first and will hit something like 30-50 damage. Then since your unit is already damaged it only does like 20-30 damage back to them and you end up losing that unit in 2 turns.
